For agencies, advertisers and media buyers
Buy advertising space directly from independent websites.
Build a shortlist from domain-verified websites, compare publisher-set packages and creative requirements, then buy without a chain of separate sales conversations.
Marketplace preview
Start with a few publisher websites.
This selection is drawn from the public marketplace. Open any website to review the packages its publisher currently lists.
Choose with context
Know where the advert will appear before you buy.
Marketplace pages connect each verified site to the campaigns and packages its publisher has chosen to sell.
Start with the website
Visit the publisher, understand its subject and decide whether the context suits your campaign.
Review the actual offer
See what is included, which creative formats are accepted and how delivery is measured.
Submit against clear rules
Supply the assets and destination required for the chosen campaign before payment completes.
For campaign teams
Turn a client brief into a defensible media plan.
Use consistent marketplace listings to evaluate direct placements without hiding who owns the inventory or receives the payment.
Compare like a media buyer
Assess each website, package, format and price against the same brief before making a recommendation.
Keep the seller visible
When a plan includes several publishers, each package payment goes to the publisher responsible for that placement.
Use shared delivery terms
Review served, rendered, viewable, clicked and invalid events using the same definitions across campaign placements.
Creative that fits the placement
Upload the banner sizes the package actually uses.
An image campaign can request one size or several, depending on the placements its publisher included. Checkout lists each required dimension, so you do not have to supply an unrelated 728×90 or 468×60 asset when that campaign does not use it.
Modern and established images
Upload GIF, PNG, JPEG, WebP, AVIF or a safely inspected SVG, subject to the size and file-limit requirements shown at checkout.
One correct file per required size
Prepare artwork at the exact pixel dimensions shown. A package can require a single square, leaderboard or other placement size—or several when its inventory needs them.
Pair the banner with its URL
For an image advert, the essentials are the correctly sized banner and the HTTPS destination it should open. The publisher then reviews the submission.
From discovery to delivery
A direct route from package to placement.
Explore websites
Browse marketplace sites and open a listing to see the campaigns currently offered by that publisher.
Choose a package
Select the quantity or duration, permitted format and placement that fit your brief.
Create the advert
Add your destination, copy and correctly sized creative. Requirements come directly from the campaign.
Pay the publisher
Complete checkout through the publisher’s connected Stripe or PayPal account. Payment creates a paid order that waits for the publisher’s decision.
Publisher review
The publisher can accept the submitted advert, request changes or decline it. A declined paid order is not refunded automatically; the publisher handles any refund through its payment provider.
Follow delivery
Use your emailed access link to see approval state, delivery progress, viewable impressions and clicks.
Useful measurement
The numbers that describe delivery.
- Served
- The delivery service selected and returned the advert.
- Rendered
- The advert was drawn in the visitor’s browser.
- Viewable
- At least half of the placement was visible for one second in an active tab.
- Clicked
- The visitor followed the tracked destination link.
- Invalid
- An event was identified as ineligible rather than silently added to billed delivery.
Advertiser questions
What happens before an advert runs.
Does opening checkout reserve an exclusive slot?
No. A single-sale campaign remains available until a payment completes. If more than one already-issued provider checkout completes, each paid order remains pending for the publisher to decide.
Does payment mean the advert is already approved?
No. Payment and publisher approval are separate. The paid order remains pending until the publisher accepts the creative; this gives the publisher a chance to check the banner and destination.
Who handles a refund if the publisher declines?
The publisher does, through the Stripe or PayPal account that received the payment. D14 does not automatically refund a declined paid order.
Will every campaign require several banner sizes?
No. Checkout requests the distinct dimensions required by that campaign’s placements. A campaign using one 200×200 placement should request only that size.
What do the reporting numbers prove?
They describe advert delivery and interaction around the placement. They do not prove a downstream sale or return on spend, so combine them with your own destination analytics.
